The invention relates to novel optionally quaternized or protonated condensation polymers having at least one heterocyclic end-group connected to the polymer backbone through a unit derived from an alkylamide, the connection comprising an optionally substituted ethylene group and to the use thereof in body care products and household products.

Polymers are gaining more and more importance, for example to improve the rheological behavior of a product or to enhance the adhesion of other ingredients to a surface such as skin, hair, nails, wood, plastic etc. Thus, there is a growing need for novel polymers suitable for use in body care products as well as in household products fulfilling the manifold requirements posed on such polymers in regard of availability, easy handling and cost/performance.

In hair care preparation for example film forming polymers are used e.g. as conditioning agent in order to improve the combability, the shine and the visible appearance of the hair as well as to give the hair antistatic properties.

Commercially available polymers for hair care such as hair styling or conditioning polymers are e.g. copolymers of vinyl acetate and crotonic acid, copolymers of methyl vinyl ether and maleic anhydride, copolymers of acrylic acid or methacrylic acid with other monomers, polyurethanes, N-vinylpyrrolidone and silicone polymers.

The aim of the invention was to provide easily available, cost efficient optionally quaternized or protonated condensation polymers having at least one heterocyclic end-group connected through the polymer backbone to a unit derived from an alkylamide, the connection comprising an optionally substituted ethylene group and to the use thereof in body care products and household products.

Polymers suitable for the incorporation into body care products or household products should exhibit a excellent heat stability, very good solubility, compatibility with cosmetic bases, pH stability in the range of 4 to 9, processability into a variety of products, compatibility with other ingredients and with the packaging materials and should be free of color and be of neutral or pleasant odor and have a low volatility.

The body care products and household products should fulfill a variety of requirements such as exhibiting low stickiness, lack of powdering or flaking, preferably being clear, transparent and glossy. Body care products such as hair care preparation should additionally fulfill a variety of requirements in regard of their performance such as providing a fine spray pattern, a good film formation, a good holding power, a high level of style retention, a prolonged curl retention, an improved combability, and should be easy to remove upon washing the hair with shampoo or soap.

It has now surprisingly been found that optionally quaternized or protonated condensation polymers having at least one heterocyclic end-group connected to the polymer backbone through a unit derived from an alkylamide, the connection comprising an optionally substituted ethylene group (in the following referred to as condensation polymer) are especially suitable for the preparation of body care products and household products.

It has also been found that they can be used as conditioning agents, strengthening agents, film forming agents, surfactants, anti-static agents, moisturizers, emulsifiers or hair styling agents.

The heterocyclic compound with a labile hydrogen atom and dialkylamine equivalent ratio can be chosen according to the ratio of NHet end-groups to dialkylamide end-groups desired in the condensation polymer. If only NHet end-groups are desired only heterocyclic compounds with a labile hydrogen atom are used in the process. If additional dialkylamide end-groups are desired the equivalent ratio of heterocyclic compound with a labile hydrogen atom and dialkylamine is generally chosen between 100:1 and 1:100, preferably between 50:1 and 1:50, most preferred between 1:10 and 10:1.

According to a further embodiment, the condensation polymer according to the invention can be obtained by a reaction between a heterocyclic compound having a labile hydrogen atom, optionally in combination with a dialkylamine, an alkanolamine and a compound containing an acid group and an activated acid group, after which a polyesteramide is obtained through polycondensation.

Preferred heterocyclic compound having a labile hydrogen atom, dialkylamine and alkanolamine have been described above.

The compound containing an acid group and an activated acid group is preferably a compound according to formula (X):

in which B is a (C₆-C₂₄) aryldiradical or a (C₂-C₂₄) alkyldiradical; L is selected from —O—(CO)—OR, —O—(CO)—R, —OR⁹, —SR⁹, —Cl in which R⁹ is a linear, branched or cyclic (C₁-C₁₂) alkyl group.

Examples of suitable compounds containing an acid group and an activated acid group are alkyl esters, such as, for example, mono(m)ethyl adipate and mono(m)ethyl sebacate, anhydrides and thioesters.

In addition to dialkylamide and NHet end-groups, the polymer may also contain carboxyl groups and/or β-hydroxyalkylamide groups. Carboxyl groups can be present in, for example, amounts of between 0.01 and 2.0 mg equivalent/gram of polymer. β-Hydroxyalkylamide groups may be present in amounts of between 0.01 and 5.0 mg equivalent/gram polymer. The amount of β-hydroxyalkylamide groups can be controlled via the ratio of alkanolamine and heterocyclic compound having a labile hydrogen atom, optionally in combination with an dialkylamine, and via the degree of conversion. If an excess of a heterocyclic compound having a labile hydrogen atom, optionally in combination with a dialkylamine, is used and the polycondensation reaction is (almost) complete, less than 0.5 mg equivalent/gram of β-hydroxyalkylamide groups are usually present. If β-hydroxyalkylamide groups are present they may in a subsequent step react with compounds containing one or more groups that can react with β-hydroxyalkylamides, such as for example carboxyl acids, carboxylic anhydrides, isocyanates, activated esters or carboxylic halides.

The degree of branching and the functionality of the polymer are dependent on the starting materials and the molecular weight of the polymer. A molecular weight higher than 2,000 and the use of di- and/or trialkanolamines generally lead to highly branched structures with a functionality of ≧6.

Due to the presence in amounts of less than 10% by weight (of the total amount of anhydrides) of bis- and dianhydrides instead of the anhydrides according to formula (VII), it is possible that the polymer does not comprise only of units according to formulas (II) and (III).

Due to side reactions during the preparation of the polymer it is possible that the reaction mixture comprising the condensation polymer according to the invention comprises also secondary amine groups, for example according to the formula (XI):

wherein R¹, R², R³ and B are defined as above.

The condensation polymer according to the invention carrying NHet end-groups can also be obtained via hydroxyl functional polymers as disclosed in EP 1 036 106. The β-hydroxylamide end-group of such hydroxyl functional polymers reacts with heterocyclic compounds with a labile hydrogen atom as defined above at elevated temperatures, preferably between 120° C. and 250° C. with water being removed, preferably through distillation. The one-step procedure can take place with or without a solvent. Suitable solvents are water or an organic solvent, such as methyl-isobutylketone, butylacetate, toluene or xylene. The removal of water through distillation can take place at either reduced or elevated pressure, such as at a pressure higher than 1.10⁵ Pa, in a vacuum (<1.10⁵ Pa) or azeotropically.

The optionally one or several nitrogen atoms of the condensation polymer which are present in quaternized or protonated forms may be prepared by reaction of the nitrogen atoms of the non-quaternized condensation polymer with customary quaternizing or protonating agents according to standard procedures as e.g. described in Jerry March, Advanced organic chemistry, 4^(th) edition, Wiley-Interscience.

Suitable quaternization agents to obtain the betaine group are chloro acetic acid and (meth-)acrylic acid. The quaternization procedure can take place with or without a solvent. Suitable solvents are water or an organic solvent, such as e.g. acetonitrile. The quaternized condensation polymer can be used as solution in the respective solvent or the solvent can be evaporated to yield a dried condensation polymer.

Suitable protonation agents are e.g. inorganic acids such as HCl; H₃PO₄; H₂SO₄; The protonation procedure can take place with or without a solvent. Suitable solvents are water or an organic solvent, such as e.g. acetonitrile. The protonated condensation polymer can be used as solution in the respective solvent or the solvent can be evaporated to yield a dried condensation polymer.

Dependent on the desired degree of the quaternization, respectively protonation, the amount of quaternization or protonation agent to nitrogen atoms has to be adjusted accordingly.

The preferred degree of quaternization, respectively protonation, of the nitrogen atoms of the condensation polymer is between 20 and 100%, more preferred between 50 and 100%, most preferred 80 and 100%.
